I've never tried before, and don't want to lose one to find out :P Are they considered armor, or can you not disenchant them? Mostly trying to figure out things like Wands, Books/relics held in offhand, rings, amulets, trinkets, stuff like that o.o;
I'm pretty sure you can disenchant rings and necklaces, I don't think you can disenchant wands or ranged weapons. No idea about librams, trinkets, or off-hands.
